This mirrors my experience almost exactly.

We focused on optimizing _signup_ conversions, succeeded and ended up in the same position as Kera.

I've been considering adding a "qualification form" during signup that evaluates whether the product is right for them, and even recommends competitors that might be more suitable for their specific situation.

Looking forward to hearing your results.

Thanks Jason, I'm looking forward to results too :)

Nice example on how to reduce the noise of signups, and zero in on a smaller group of prospects. Thanks!

No problem. The other big thing we're trying to tackle is how to move a customer through our activation funnel after they signup. That's another thing that is tricky when you have a half-baked product.
